Judgement
- What it is
- Developer tool
- What it does
- An end-to-end and component testing tool that runs tests inside the browser with a visual runner showing each step, time travel and automatic waiting.
- Adopt it when
- Your front-end team wants an easy-to-debug browser test tool with an interactive runner, mainly for Chromium-family browsers.
- Watch out
- Multi-tab, multi-origin and Safari testing are weaker than in Playwright, and parallel runs and analytics are pushed to the paid Cypress Cloud.
- Ready for
- Production-ready
- Runs as
- Command line, desktop app and cloud service
- Built with
- TypeScript, Electron and Node.js
- How established
- Established: started 11 years ago, latest release v16.2.1.

Open-source alternatives to Cypress

1
Browser Use browser-use
Open-source Python library for AI browser agents, plus Browser Use Cloud: stealth browsers and a hosted agent API.
Building block Usable You are building an AI agent that has to complete tasks on websites that have no API, and you accept slower, less predictable runs than a scripted Playwright test.

Playwright microsoft
Playwright is a framework for Web Testing and Automation. It allows testing Chromium, Firefox and WebKit with a single API.
Developer tool Production-ready You need reliable end-to-end tests across all major browser engines, or browser automation for scripts and AI agents.
★ 99k Apache-2.0 TypeScript Active, pushed today

Puppeteer puppeteer
JavaScript API for Chrome and Firefox
Developer tool Production-ready You automate Chrome from JavaScript for scraping, PDFs or screenshots and do not need Safari's engine.

Lightpanda lightpanda-io
Lightpanda: the headless browser designed for AI and automation
Developer tool Usable You run many headless sessions for scraping or AI agents and want far less memory and startup time than headless Chrome.
★ 41k AGPL-3.0 Zig Active, pushed today

5
Selenium SeleniumHQ
A browser automation framework and ecosystem.
Developer tool Production-ready You need to drive real browsers through the WebDriver standard, use languages beyond Playwright's, or run a large existing Selenium suite or Grid.

CloakBrowser CloakHQ
Stealth Chromium that passes every bot detection test. Drop-in Playwright replacement with source-level fingerprint patches. 50+ tests passed.
Developer tool Usable Your scraping or agent runs are blocked by bot detection that catches stock headless Chrome and you have a legitimate right to the data.
